If you are hooked up to a municipal water supply, make sure you get a 3/4" diameter hose instead of the "standard" 5/8 diameter. You`ll be able to take advantage of the water pressure from municipal supplies and get a higher water flow rate.
This higher flow rate may be an advantage (and needed) if you use a larger high-pressure small engine-driven power washer. If you have an electric power washer, a 5/8 diameter will supply a sufficient amount of water flow.
